The JDSU Agile Transmission Modules family includes tunable transponders and tunable lasers. The flexibility enabled by JDSU's transponders is critical to the successful and rapid deployment of next generation, IP-based voice, data and video services which are driving new network management challenges for communications service providers. They also support applications, from ultra long haul to metro networks, in a single platform.
The 7100 series 10 Gbps Universal Transponders are MSA compliant, widely tunable, long-reach modules incorporating a transmitter and receiver in the same physical package. The user can choose either a full C-band or full L-band module. The module has a 300-pin connector for the electrical interface and two fiber pigtails (with user-specified optical connectors) for optical input and output ports. The module is compliant with ITU 691 STM-64 L-64.2a and Telcordia GR-253 Issue 3 LR2-c for optical interface, and with OIF-SFI4-01.0 (previously OIF99.102) for the electrical interface.
In the transmit direction, the transponder module multiplexes sixteen 622 to 693 Mb/s electrical signals into a single 9.953 Gbps to 11.1 Gbps signal, which is then modulated onto the optical transmitter output. The optical output meets or exceeds the SONET specifications stated in Telcordia GR-253 Issue 3 and draft ITU-T G691 and G.692. The wavelength of the optical transmitter is user programmable over the full C-band or L-band using commands sent via the I2C™ interface. The transponder module synthesizes a high frequency clock (9.953 to 11.1 GHz) from either a 155 to 173 MHz or a 622 to 693 MHz input clock, selected by the user.
In the receive direction, the transponder module accepts a 9.953 to 11.1 Gbps optical signal and converts it, using a clock and data recovery circuit, into an electrical equivalent. This electrical signal is then demultiplexed into sixteen 622 to 693 Mb/s output signals and its associated clock.
